Back Touch Panel Input Control for Intuitive Game Device Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input methods for smartphones and portable game devices with touch panels lack user-friendliness and operability, necessitating a more convenient input control technique to enhance user experience.
Innovation Solution
An input control program that functions as a display controller, acquiring and determining input positions from both the touch panel and back touch panel to operate display targets, adjusting operation directions based on the type of display target and input type, thereby providing intuitive and consistent user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel is provided only on the front side of the display device, then the device structure is simple, but the operability and user-friendliness are insufficient
Solution Approach 1:
The patent applies dimensionality change by adding a back touch panel on the rear side of the display device, transforming the input interface from a single-plane (front-only) structure to a multi-plane structure. This allows users to interact with the device from both front and back surfaces, enhancing operability without complicating the overall device architecture.
Solution Approach 2:
The back touch panel serves multiple functions: it enables input operations from the rear side, provides additional interaction areas, and maintains consistency with front panel operations. This multi-functionality approach allows the same input methods (tap, swipe, pinch) to work on both panels, improving ease of operation without requiring separate control schemes.
2Ease of operation
If different operation directions are used for front and back touch panels, then each panel can be optimized for its side, but the user experience becomes less intuitive and consistent
Solution Approach 1:
The patent implements homogeneity by making the operation directions on the back touch panel consistent with those on the front touch panel. For example, an upward swipe on the back panel produces the same scrolling effect as an upward swipe on the front panel. This uniform behavior across both panels enhances user intuition and reduces cognitive load, while the control logic handles the consistency automatically.
3Ease of operation
If basic touch panel operations are used, then the implementation is simple, but the user-friendliness and convenience are insufficient for future expectations
Solution Approach 1:
The patent applies dynamics by enabling flexible and adaptive input operations on both touch panels. The system dynamically responds to various gesture types (tap, swipe, pinch, rotate) and adapts the operation based on the detected gesture and the current display context. This dynamic behavior enhances user-friendliness while maintaining manageable control complexity through standardized gesture recognition algorithms.

AI summary
A game device includes a screen generator that displays a display target on a display screen of a display device, an input acquirer that acquires the position or direction of operation input to the display target from a touch panel annexed to the display screen of the display device and a back touch panel provided on a surface on the opposite side to the display screen of the display device, a determining section that determines the direction in which to operate the display target according to the position or direction of the operation input and the kind of the display target as the target of the operation when the input acquirer acquires the operation input to the display target from the back touch panel, and a movement controller or a rotation controller that operates the display target in the direction determined by the determining section.
